For the zener diode shown in the figure, the zener voltage at the knee is 7V, the knee current is negligible and the zener dynamic resistance is 10Ω. If the input voltage (Vl) range is from 10 to 16V, the output voltage (Vo) ranges from

1.

7.00 to 7.29V

2.

7.14 to 7.29V

3.

7.14 to 7.45V

4.

7.29 to 7.45V

Solution

Answer:

In addition to Zener diode voltage, some voltage drop also takes place due to dynamic resistance
